TRANSLUCENT PYROTECHNIC DEVICE Filed Feb. 11 1932 INVENTOR 10A,? 6. Moore iizwwijmw.

his ATTORNEY Patented Feb. 28, 1933 NETE TRANSL'UCENT PYROTECHNIC DEVICE Application filed February The present invention relates to pyrotechnic devices and has for its principal object the formation of a device of this character, in which an illuminating element situated interiorly of a body or casing will provide a means for bringing to view a pictorial representation located in a translucent area thereof, so that the pictorial representation becomes observable from the exterior of the device to persons witnessing the display.

Another object of the invention is to normally conceal the pictorialrepresentation so that its exact characteristics will be retained as a surprise to the observers until the actual ignition of the illuminating element associated with the pyrotechnic device.

Still another object is to effect the operation of the illuminating means providing the surprise subsequently to the firework display.

Other objects and advantages of the invention will become apparent as the description proceeds.

Referring to the drawing:

Fig. 1 is a side elevation of an improved pyrotechnic device made in accordance with the present invention.

Fig. 2 is a sectional elevation of the device as illustrated in Fig. 1.

Fig. 3 is a front elevation of the pyrotechnic device as it appears during the operation of the illuminating element.

The pyrotechnic device embodying the present invention is illustrated in the drawing in its preferred form, the body or casing of the device being indicated at 10. The casing is conical in shape in this instance and is preferably open at its apex for purposes hereinafter described and is closed at its base by an element shown in the drawing at 11. A tubular member 12 containing a suitable pyrotechnic compound is located interiorly of the casing inclosure, one end of the same coinciding with and substantially occupying the entire area afforded by the opening at the apex of the casing. A fuse 13 is situated at the open end of the tube and extends out of the casing to provide means for igniting the pyrotechnic compound within the tubular member. Upon the ignition of the fuse, a

firework display is produced exteriorly of the casing in the usual manner.

An illuminating element 14 is associated by means of a fuse 15 to the inwardly disposed end of the tubular memberlQ. The end of the fuse 15 is ignited by the burning pyrotechnic compound in the tube, so that subsequently to the firework display exteriorly of the casing the illuminating element 14 will be brought into 01 eration. The open tube 12 will then afford ready access of the expanding gases, issuing frcm the illuminating element after ignition, to the atmosphere.

A. portion of the casing 10, oppositely disposed to the illuminating element 14 enclosed therein, is cut away as indicated at 16. This cut-away portion of the casing 16 is covered to provide a translucent area therein, which is accomplished by the use of parchment 17 or other suitable material permitting the passage of light therethrough. The interior face of the parchment contains a pictorial representation 18 such as for purposes of illustration is shown in Fig. 3 of the drawing to depict a portrait, of the head of George Washington.

In order to'improve the appearance of the device externally and to insure that the pictorial representation be entirely concealed from View until after ignition of the fuse 15, the casing is covered by an attractively colored tissue paper indicated at 19. It is apparent that subsequently to the firework display and upon ignition of the illuminatelement, that the pictorial representation situated in the translucent area of the casing will be observable from the exterior of the device.

From the foregoing description taken in connection with the accompanying drawing,

construction and operation of the invention will be readily understood Without requirin g a more extended explanation. Various changes in the form, proportion and details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as claimed. It will also be understood that the pictorial representation utilized in the translucent area may be of any desired nature in keeping with the occasion or circumstances in which the pyrotechnic device is operated.

What I claim and desire to secure by Letters Patent is:

1. A pyrotechnic device comprising a conical casing having a translucent area therein, a normally concealed pictorial representation situated in said translucent area, means for efi'ecting a pyrotechnic display exteriorly of the casing, and means for subsequently illuminating the interior of the casing so that the pictorial representation will appear to view.

2. A pyrotechnic device comprising a casing inclosure with atranslucent area therein, a normally concealed pictorial representation situated in said translucent area, means for effecting a pyrotechnic display exteriorly of the casing, and means for illuminating the interior of the casing so that the pictorial representation will appear to view.

3. A pyrotechnic device comprising a conical casing having a translucent area therein, a normally concealed pictorial representation situated in said translucent area, a tubular member containing a pyrotechnic compound located within said casing, one end of the tubular member coinciding with an opening at the apex of the casing, means for igniting the pyrotechnic compound and producing a firework display exteriorly of the casing, illuminating means associated with said tubular member operative subsequent to the firework display whereby the pictorial representation will appear to view.

4. A pyrotechnic device comprising a conical casing having a translucent area therein, a normally concealed pictorial representation situated in said translucent area, a tubular member containing a pyrotechnic compound located within said casing, one end of the tubular member coinciding with an opening at the apex of the casing, means for igniting the pyrotechnic compound and producing a firework display exteriorly of the casing, illuminating means connected by the fuse to the other end of the tubular member whereby subsequent tothe firework display the pictorial representation will appear to View.

5. A pyrotechnic device comprising a casing inclosure with a translucent area therein, means for elfecting a pyrotechnic display exteriorly of the casing, means for producing illumination interiorly of the casing, a pictorial representation situated in the translucent area observable from the exterior of the device upon operation of the means for producing illumination.
